Our each Guides module involves an average of 50 images for media panel content. All of them are photos converted to JPEG/PNGs.
The microsoft documentation shows 854x480 resolution for an MP4 video. Should we maintain same aspect ratio for the images too?
Using JPEGs instead of PNGs saved us roughly 40MB file size for ~60 images.We would like to know more about "best performant" approach forimage format, size, resolution & compression.
Please refer to the following documentation which describes the limitations to the media.
Supported file formats for 3D models, images, and videos in Dynamics 365 Guides - Dynamics 365 Mixed Reality | Microsoft Docs
And here are the General notes for images.

Problem is that we always end up with huge assets with multiple steps. In our case, images play important role since we use them in high volume.
Would a 72dpi image consume less runtime memory than a 96/150 dpi image?
Will 854x480 scale better with less memory than a 1080p?
We would like to know which image format & compression type will perform better.
Please help us in choosing the "best performant" approach for media panel images.
Hi, if you import images using the Guides PC tool then the images will always be automatically resized to a maximum of 1024 x 576 for display on Hololens regardless of the original image DPI.
JPG is a better choice for photographic images and PNG is generally a better choice for illustrations with large blocks of solid color as those two formats are optimized for different scenarios and will result in smaller file sizes for storing in DataVerse and faster downloading to the Hololens. You can see the actual size of the uploaded files by looking in the Dynamics portal for Guides.
However both formats will use exactly the same amount of memory on the Hololens when you come to load the guide.
Hope that helps,
Thank you Stephen, this is much useful!
Since we moved from other game engine platform, we are trying to understand more about how Guides engine works. This will help us implement large complex procedure modules efficiently.
